Grain Mill: construction, grain and storage

The Grain Mill takes ingredients from its own storage, not directly from the bank. Wheat sitting in the bank does not keep a depleted mill running. Finished products go to the bank, which needs room for the selected output.

Build it before buying its supply chain

The recorded construction requires Farming 10 and 750 each of Oak Logs, Stone and Molten Glass. Construction also opens the Mill Farm category for Wheat and Sugarcane; buying a growing plot is a separate expense.

Base recipe	Input inside mill	Output per cycle
Flour	10 Wheat	50 Flour
Basic Grain	10 Wheat	20 Grain
Sugar	10 Sugarcane	50 Sugar

Flour supports Cooking. Grain supports animal feeding. Selecting the wrong output can consume the same Wheat stock while failing to prepare the Ranching session you intended.

Follow both inventory boundaries

The base mill storage holds 6,000 of each item stack. With 120 Wheat loaded, the two Wheat recipes each have ingredients for 12 cycles. Before output modifiers, that is 600 Flour or240 Grain, rather than both. Another 1,000 Wheat in the bank does not extend those 12 cycles until moved into the mill.

The mill does not roll output doubling or ingredient preservation in this snapshot. Do not apply a normal artisan recipe’s bonus assumptions to its cycle count. Use the mill’s displayed interval for timing; these ingredient totals do not establish a per-hour rate.

Reserve bank space for finished products

A mature Farming crop remains ready if it cannot be harvested into the bank. Reserve output space for the mill before an unattended session, even when its ingredient storage has plenty left. Its separate storage does not add capacity to the bank.

Stop the Mill & Collect before changing its selected product. Then check the new ingredient and destination stocks. This prevents a correctly loaded mill from continuing to make Flour when the immediate shortage is animal feed.
